multiple destinations or recipients simultaneously. The following types of messages are supported by
the feature:
• Status messages (including Emergency Alarms)
• GPS LIP (TETRA Location Information Protocol) reports
• RMS/FMS messages
• Bluetooth Sensor Addressing
Shadow Groups in TMO
Each Shadow Group may contain up to four target addresses. Each talkgroup may be configured to
send status messages, GPS LIP reports, or RMS/FMS messages to a specific Shadow Group.
Shadow Groups in DMO
In DMO, the Shadow Group contains one target address. Each talkgroup may be configured to
send status messages or GPS LIP reports to a specific Shadow Group.
Each radio can store up to 255 Shadow Groups (both in TMO and DMO).
